Full Specifications

EA-37B Compass Call Electronic Warfare Aircraft

The EA-37B Compass Call is the US Air Force’s newest dedicated electronic warfare aircraft, built to dominate the electromagnetic spectrum in modern conflicts. Designed to replace the aging EC-130H fleet, the EA-37B focuses on jamming, disrupting, and degrading enemy command, control, communications, radar, and navigation systems. Rather than carrying weapons, its mission is to blind and silence adversaries, enabling US and allied forces to operate freely across contested battlespaces.

Manufacturer

The EA-37B is manufactured by L3Harris Technologies, with the airframe based on the Gulfstream G550 business jet produced by Gulfstream Aerospace. The electronic attack mission systems are developed and integrated in the United States, making the aircraft a core element of US Air Force electronic combat modernization.

Speed and Range

Thanks to the G550 platform, the EA-37B offers significantly higher speed, altitude, and range than its predecessor. It can cruise at high subsonic speeds and operate at altitudes above 40,000 feet, extending its electronic attack reach. The long range allows global deployment with fewer aerial refueling requirements, improving responsiveness during crisis operations.

Cost / Price

The estimated unit cost of the EA-37B varies by configuration but is generally assessed at over USD 300 million per aircraft, including advanced electronic warfare systems, sensors, and mission integration.

Key Capabilities

The EA-37B carries a highly classified electronic warfare suite capable of targeting multiple frequency bands simultaneously. It supports cyber electromagnetic activities, joint force operations, and suppression of enemy air defenses without entering heavily defended airspace.
